UMTS has evolved first into LTE and then into an enhanced version known as LTE- Advanced The chapter closes by reviewing the standardization process for LTE 1.1 Architectural Review of UMTS and GSM 1.1.1 High Level Architecture LTE was designed by a collaboration of national and regional telecommunications standards bodies known as the Third Generation Partnership Project (3GPP) [1] and is known in full... I am indebted to Michael Salmon and Geoff Varrall, for encouraging me to write this book, and to Michael Salmon and Julian Nolan, for taking time from busy schedules to review a draft copy of the manuscript and for offering me invaluable advice on how it might be improved I would also like to extend my thanks to the delegates who have attended my training courses on LTE Their questions and corrections... software, and passes it to the next layer down by representing it in a way that the user’s application layer will eventually be able to understand Other application layer protocols include the simple mail transfer protocol (SMTP) and the file transfer protocol (FTP) The transport layer manages the end -to- end data transmission There are two main protocols The transmission control protocol (TCP) re-transmits...
